In Argentina June 9, 1933 1 Claim.

This invention relates to devices for condensing oil from vapors originating in the crank case of an internal combustion engine and separating this oil so that the uncondensed vapors may be carried to and utilized in the carburetor of the engine.

The object of the invention is to provide an oil reclaimer and separator which is adapted at one end to be connected to the crank case of the engine and receive oil laden vapors therefrom and which at the other end is adapted to be connected to the carburetor of the engine, the

separator itself constituting a casing through which the vapors travel in a circuitous course.'

the casing being inter'sected or traversed by closely adjacent air tubes extending entirely through the casing, preferably in the direction of travel of the automobile and being open at their-opposite ends sothat cool atmospheric air may pass thru these tubes and thus act to cool and condense the vapors carried into the casing.

Our invention is illustrated in the accompanying drawings whereinz- Figure 1 is a side elevation of our reclaimer and separator, a side wall being partly broken away: Figure 2 is an end elevation of the structure shown in Figure l..

Referring to these ngures, ldesignates thev casing of our improved separator, this casing being preferably cubical in form and being relatively narrow. Extending through the casing from one'end to the other and disposed very closely adjacent to each other are the air tubes 2, which open at their ends, as at 3, upon the front and rear of the casing so that as the automobilev travels, fresh atmospheric air may be forced through these tubes 2.

The casing at one end is provided with an inlet opening in its bottom into which extends a pipe 8, which leads from the crank case of the engine (not shown). Extending from the top of the casing at the end opposite the inletopening is the outlet pipe 9, which may lead to the carburetor of the engine. Extending upward from the bottom l0 of the casing is a baille plate 6 which terminates short of the top of the casing v and which is disposed just beyond the inlet pipe 8. Extending downward from the top of the casing is a baille plate l which terminates short of the bottom I0 of the casing and which is dis-l posed at its upper end adjacent the outlet pipe 9. 'I'he tubes 2 extend through these baille plates 6 and l.

(oil 257-36) then again upward before passing out through the outlet pipe 9 and in this circuitous course the vapors come into intimate contact with the cool air pipes 2 and any oil or readily condensable liquid which may be carried in with the vapors is condensed and this oil drops downward onto the bottom i0. The bottom i0 is inclined, as shown in Figure 1, or sloped downward toward one end of the casing and at this end'of the casing there is an opening discharging into a collecting receptacle il, shown as supported by means of a yoke i2. Oil may be drained from the collecting receptacle at any time for reuse.

It is designed that this casing be disposed closely adjacent to the engine so as to receive heat therefrom whereby the heat radiated from the motor will induce an advantageous temperature in the chamber or casing.

We claim:

An -oil reclaimer and separator for internal combustion engines, comprising a relatively narrow casing disposed in vertical position and having broad side walls and narrow top, bottom and end walls, said bottom wall being disposed at an inclination, air tubes extending through the casing between said end walls and parallel with the side walls thereof, a baille plate extending upwardly from the bottom wall toa poin't short of the top wall and connecting the side walls and having the air tubes passing therethrough, a second baie plate extending downwardly from the top wall in spaced relation with the iirst bae plate and terminating short of the bottomwall and connecting the'side walls and having the air tubes passing therethrough, an oil vapor inlet through the bottom wall adjacent the highest end thereof, an outlet for the casing through the top wall adjacent the opposite' end from the inlet, said bottom wall at, its lowest end having an outlet opening and a downwardly extending ange surrounding the same, an oil receiving cup having a mouth adapted to position over said last opening within the ange, and a bail oscillatably attached to said ange and adapted to be positioned beneath said cup to retain the.

latter inoperative position.
